Yes.

Not at all. He was dismissed because they looked, looked and looked but found no evidence of widespread fraud. He then reported as much. That report was inconsistent with what the POTUS wanted to hear.

Theoretically, slaughterbots could be made to kill all men, or all women, or all children, or all people with a certain hair colour, or all people who posted disapproval of great leader X in a social network feed, or all people who pirated the latest release of TV-series Y, or everyone with a Slashdot ID over a million, and so on and so forth.

There's no end to what could trigger a cell/organisation/nation/whatever to strike with drones in that fashion.

That is one of the points the video tries to make.

The barrier to entry is soon so low and the tech is getting so advanced yet widely available that domestic drone strikes can soon be just another terrifying part part of our daily life.

Excerpt from an interview with a dev who knows how to deal with this problem:

Neo: Do you always look at it encoded?

Cypher: Well you have to. The image translators work for the construct program. But there’s way too much information to decode the Matrix. You get used to it. II don’t even see the code. All I see is blonde, brunette, red-head. Hey, you uh want a drink?

What about investigations into the crimes that US troops (among others) and people higher up in the chain of command have conducted?
Why do they never get put on trial and punished?

Naive to think that they ever will be perhaps, but still...

You want to go back to the type of society you had back in the days of, for example, Truman and Nixon? That almost got us a third world war.

Get a grip.
